Production of moldings from an inorganic-organic hybrid polymer with high resolution by means of 3D printing, moldings with high flexural strengths and elastic moduli and their use for dental purposes

摘要

The invention relates to a method for producing a shaped body with the aid of a radiation-induced printing process according to the technique of the one-photon polymerization process, characterized in that the shaped body is produced by solidifying a liquid or viscous material which is a polysiloxane component which with hydrolytic condensation of one or more monomeric silanes with only two or three hydrolyzable groups and at least one organically polymerizable radical which is bonded to the silicon atom via carbon and was formed and contains an initiator and / or catalyst for the radiation-induced polymerization of the organically polymerizable radical , and- the solidification takes place in that light from a radiation source is directed onto an area of a surface of a substrate, a layer of the liquid or viscous material located there being exposed to the radiation of an orga African polymerization and is thereby solidified, whereupon further layers of the liquid or viscous material, which are each on the layer of the last solidified material, are solidified with the aid of this radiation source. The invention also relates to a shaped body based on an organically polymerized silica ( hetero) polycondensate, which was produced by organic polymerization of the polysiloxane component mentioned, with superior mechanical properties
